In the unlikely event that someone has a billion+ scripts (or some
codepath returns negative numbers), we could overflow and make a pile of
errors a non-error. This change also allows us to use flags for the
error in the future rather than just "something went wrong".

Fix capitalization of Qt4_FOUND variable when setting it to false in
this case. This caused find_package(Qt4) to appear successful when it
was not. Note that the legacy QT4_FOUND variable is unconditionally
overwritten at the end of the file with the value of Qt4_FOUND.
The use of FeatureSummary inside a find module is not a convention
yet used by upstream CMake modules. Drop the example from the
documentation about how to write find modules. If in the future
we add use of FeatureSummary to many of the upstream find modules
then this example can be restored as part of establishing the
convention.

We use cmGlobalGenerator::GetDirectoryContent to avoid repeating
directory listings. However, GetDirectoryContent loads content from
disk at most once. This breaks find_library calls that occur when disk
content has changed since preceding find_library calls.
Teach cmGlobalGenerator::GetDirectoryContent to save the directory
modification time when content is loaded and re-load content if it
changes.
Create a RunCMake.find_library test with a case covering this.
Given a rule of the form
out1 out2: dep1
out1 out2: dep2
Borland Make complains that there are multiple rules for "out1"
even though this works when there is only one output. Instead
generate
out1 out2: dep1 dep2
for Borland Make, but only when there are multiple outputs.
Set CMAKE_C_STANDARD and CMAKE_CXX_STANDARD only if they are not
already defined. This will allow users to add the settings with
different values to their local cache (e.g. on the command line).
In commit v3.1.0-rc1~484^2 (Help: Format and revise file() command
documentation, 2014-05-23) the signature of file(GENERATE) was
accidentally simplified too much and dropped specification of the
required argument ordering. Restore the signature to make the order
clear.
Convert the StringToInt helper into a StringToLong helper with a 'long'
result type. This will make the helper more useful to other callers
that want to use strtol.
While at it, also check errno after calling strtol in case the
conversion fails with a range error.
Because ctest reads in binary but writes in text mode, Windows' newline
transformation can be applied multiple times causing '\n' in the source
application to be written out as '\r\r\n' instead.

Extend the BuildDepends test with a case covering multiple custom
command outputs with the second one consumed by another rule. With the
old "multiple output pair" infrastructure used in the Makefile and Xcode
generators this did not work. Now that it is fixed, test the case
explicitly.
Fix the generated makefiles for custom commands with multiple outputs to
list all the outputs on the left hand side of the build rule. This is
much simpler and more reliable than the old multiple-output-pair
infrastructure.
The Xcode generator uses Makefiles under a run-script build-phase to
drive custom commands. Fix the generated makefiles for custom commands
with multiple outputs to list all the outputs on the left hand side of
the build rule. This is much simpler and more reliable than the old
multiple-output-pair infrastructure.
If this option is enabled, the test step is created with the
EXCLUDE_FROM_MAIN option, and if TEST_BEFORE_INSTALL is enabled, the
install step does not depend on the test step.
This means that the test step is never executed, unless the test target
is explicitly created by calling ExternalProject_Add_StepTarget, or by
passing it with the STEP_TARGETS option, or with the EP_STEP_TARGETS
directory property.
